Hanoi, 12 October 2026. The reading room of the chess club on Hang Bai Street had one yellow bulb left and four people around the long table. On the table lay a thin stack of books that had just come in from the warehouse, their spines still smelling of fresh ink. The boy at the end of the table — myself, sixteen years old — bent over a notebook with a worn cover, copying out by hand, line by line, a Petrov variation.
The older player beside me flipped through a few pages and spoke half as a complaint, half as a warning: "Every month there are new books. We cannot copy fast enough, and we cannot read them all either." That sentence stayed with me for nearly half a century. The difficulty for a chess student was never a shortage of material. The difficulty was knowing which material was worth copying.
Context
In October 2026, chess material reached Vietnam on a steady rhythm: one batch a month, most of it translated or adapted from Russian, a smaller part written by domestic coaches for the amateur movement. This month's batch separates into three clean groups: an updated theoretical file on the Petrov Defence, two volumes on positional play, and a set of lectures on calculation.

The Petrov Defence — sometimes called the Russian Defence — begins 1.e4 e5 2.Nf3 Nf6. It is named after Alexandre Petrov, a Russian player who lived from 1794 to 1867 and was the first to analyse the system systematically. Unlike most classical defences, the Petrov does not retreat to protect the e5 pawn. Black answers an attack with an attack, aiming straight at White's e4 pawn.
That explains why the system has survived so long, and also why it constantly needs refreshing. This is an opening in which a single move out of tempo is enough to turn a symmetrical position into a passive one.
The October batch arrived at a notable moment: Anatoly Karpov had held the world championship since 2026, and a whole generation of students was trying to understand how a solid, low-risk style could win at the highest level. The Petrov is one answer, though only part of an answer.
Analysis
Reading the three groups closely reveals a familiar structure, one any editor recognises: the content is divided along two axes. One axis is opening theory — the part that belongs to a specific game, a specific opponent, and expires within months. The other is transferable skill — calculation, decision-making, positional feel — the part that belongs to the player and stays for life.

Opening theory holds its value for months; calculation and positional feel are what pay interest for the rest of a player's life. A Petrov update does not teach a student how to win. It teaches a student how not to make themselves weaker in the first fifteen moves. That is a modest goal, and it is the goal most amateur players fail.
The presentation follows the three-layer model that has become the standard: theoretical explanation, annotated real games, and practical exercises. No layer can be dropped. Without the annotations, theory goes dry. Without the exercises, a reader understands but cannot execute. Without the explanations, the exercises become riddles.
Another point worth noting: the material is divided by playing strength. What is written for the amateur movement is not what is written for the national squad, and the compilers plainly understood the difference. A body of teaching material that wants to survive must serve several levels of reader at once, rather than only the group that is already strong.
And one more thing I have observed over many years in this trade: author diversity is not accidental. Three different writers, with different voices, different schools and different ways of seeing a board, appearing in the same batch, is a way of covering a wide readership. The beginner finds patience; the tournament player finds depth; the coach finds material to teach with.
A Contrary View
There is one detail in the October batch that deserves more attention than the rest: two volumes on positional play, released in the same month. People usually read that as a sign of abundance. My experience says otherwise. Two books on the same subject in the same batch is more often a sign of duplication — either two ways of saying the same set of ideas, or two halves of one book split apart for reasons that have nothing to do with chess.
And there is something harder to say. These materials are introduced by the same institution that produced them. The people who make the books write the praise for their own books. That does not make the praise false, but it does mean the praise has not been independently verified. A good book does not need its author to praise it; it needs a second reader willing to say plainly that chapter seven is badly written.

One thing also needs saying plainly about the Petrov, because a myth has grown around it. People believe the Petrov is the "safe" opening, that choosing it means choosing calm. This is not true. The Petrov is not safe; it is only slow. A passive player holding Black in the Petrov will lose exactly as they would holding Black in any other opening — the difference is that death arrives later, and because it arrives later it is harder to notice. Certainty and timidity can look identical on a chessboard, but they do not end the same way.
In that reading room there was an old coach, hands trembling, still writing down every line. For twenty years he had chosen low-risk openings and never changed them. An old bird understands that landing is also a way of flying.
Conclusion
What deserves watching in the coming months is not the number of titles but whether anyone stands outside this stream of material to verify it. When the board holds no more moves, memory begins to make its first ones. And the chess-book trade, in the end, remains a place where people sell theory to buy hope.
So a student of chess in 2026 should probably ask a different question: beyond the first fifteen moves, what have you prepared for move twenty?
